Can I suggest Add-on here?

I would like the following add-ons:

Would be helpful to be able to see the age of a webpage, esp. reviews etc.

would like to be able to check whether a page is Fake News or reliable info.

Thank you.
You people are doing a very good job.

About #2: I would suggest not using an extension or a website to tell you what is fake news. It’s better to check facts yourself, because fact checkers can have false positives/negatives or worse, be biased.
If you are still interested in one, there seem to be two extensions available for this purpose (I haven’t tried either)
